The GY611 gyro is an AVCS ( Angular Vector Control System) rate gyro developed for model helicopter competition.
【GY611 gyro】
●Super narrow pulse (760us) drive system substantially improves servo response. An S9256 digital servo is used.
●Microcomputer high-speed arithmetic processing substantially improves gyro response.
●High resolution 12-bit A/D accurately converts the sensor output to a digital signal.
●Newest SMM (Silicon Micro Machine) and low-back aeroform case improve vibration resistance and neutral characteristic.
●Amp mounts an LCD that allows accurate data setting.

【BLS251】
Equipped with a brushless motor that lasts longer and operates at a
lower temperature than brushed motors
Samarium cobalt magnets and dual ball bearings
Same power consumption and centering as digital servos equipped with brushed motors
Standard size
